Eat This Now: Avocados

Good for YouSome runners avoid avocados because they're high in fat (one cup of the sliced fruit contains 21 grams). But nearly all of that comes from the heart-healthy kinds called mono-and polyunsaturated fats, which, when eaten in place of saturated or trans fats, can actually help lower LDL (so-called "bad" cholesterol) levels.

Get the BestChef Daniel Humm advises choosing avocados that are slightly soft to the touch, but not too mushy. "After two days at room temperature, they'll ripen and be perfect," he says. Hass avocados, one of the most common varieties, have pebbly skin that turns from green to purplish-black when ripe and have a creamy taste. If you don't use ripe avocados right away, store them in the refrigerator to keep from spoiling.

Kitchen SimpleGuacamole is an easy way to enjoy avocado, says Humm. Mash two avocados and stir in two tablespoons diced red onion, a half cup diced tomato, half a minced jalepeno, two minced garlic cloves, a half cup chopped cilantro, three tablespoons lime juice, salt, and pepper. Serve with chips and veggies, or spread on sandwiches.
